Abstract
A process for producing an oxygen reducing catalyst including a step of heat-treating, in a non-oxidizing atmosphere, a catalyst precursor including a compound (i) supplying a carbon element and a nitrogen element by heating in a non-oxidizing atmosphere, and a compound (ii) containing at least one element of iron and cobalt. Also disclosed is an oxygen reducing catalyst, a fuel cell catalyst layer including the oxygen reducing catalyst, an electrode including the fuel cell catalyst layer, a membrane-electrode assembly including the electrode and a fuel cell including the membrane-electrode assembly.
